Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing and add richness as they set gently with the warm mixture.
- Milk
- Forms the liquid base that thickens with the heat and yolks.
- Vinegar
- Adds acidity that gives the dressing its tangy flavour.
- Sugar
- Balances the acidity of the vinegar with a touch of sweetness.
- Butter
- Adds fat for a smoother, richer mouthfeel.
The step that matters
Cook the mixture gently while stirring constantly. Milk and egg yolks can curdle or scramble if the heat is too high or stirring stops. Constant stirring over medium heat lets the mixture thicken evenly into a smooth, creamy dressing.
